前几天写了一篇键盘记录器,好多人反映看不懂,
3 z& `) @) B' V7 x& r0 a对新人没什么用处,所以且这篇我会写的
5 s7 _, O% B, s1 n6 g很详细,再也不像那篇,出了代码什么也没 ^!^1 i, h" ~2 I. O% h" I# L! g
这个程序将会详细的讲解如何记载键盘的每一次输入。6 |& ?% k! e! v1 u4 z- E0 M
下面介绍的这个程序主要是利用GetAsyncKeyState函数,
8 h! h6 X1 O/ N7 ^# Q: C使用GetAsyncKeyState可以获得键盘的动作。
$ {5 C6 N: A+ mGetAsyncKeyState函数根据虚拟键表判断按键的类型。% b" e) Z9 U) r. F6 V+ r3 K( E! d# e# R
返回值为一个16位的二进值数,如果被按下则最高位为1,
/ v- |$ H: s4 `即返回-32767。下面是API函数及鼠标中左右键在虚拟键表中的定义:" @; Q3 _8 y% q. X
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer$ r% j& x5 {0 N0 d" |
